In general, EEPROMs support I2C interface. In that case PSoC should act as an I2C Master and the EEPROM device as a slave.

Some EEPROM devices also have the provision of setting their addresses (last 2 bits or so) externally, so that multiple EEPROM devices can be made available on the same bus thereby increasing the memory available.

The version of creator i am using is Creator 2.0. may be the project was not compatable so i got the following error.

Error: sdb.M0062: An error occurred trying to retrieve the DRCs for an instance, 'I2C'. Unable to locate and customize component 'I2C_v3_30' used in schematic 'C:\Documents and Settings\Adm\My Documents\PSoC Creator\Example_I2C_EEPROM\Example_I2C_EEPROM.cydsn\TopDesign\TopDesign.cysch'.

Actually i am using Del Sig ADC with 8 bit resolution, 8500 SPS, and it will run for 5 seconds so i get too many samples but the RAM avalaible in PSoC 3 is 8 kb only, so i am going for EEPROM interface to accomodate so many samples , is this a correct option any other way?
